Fibromyalgia is a chronic pain syndrome characterized by dysfunctional processing of nociceptive stimulation. Neuroimaging studies have pointed out that pain-related network functioning seems to be altered in these patients. It is thought that this clinical symptomatology may be maintained or even strengthened because of an enhanced expectancy for painful stimuli or its forthcoming appearance. However, neural electrophysiological correlates associated with such attentional mechanisms have been scarcely explored. In the current study, expectancy processes of upcoming laser stimulation (painful and non-painful) and its further processing were explored by event-related potentials (ERPs). Nineteen fibromyalgia patients and twenty healthy control volunteers took part in the experiment. Behavioral measures (reaction times and subjective pain perception) were also collected. We manipulated the pain/no pain expectancy through an S1–S2 paradigm (cue-target). S1 (image: triangle or square) predicted the S2 appearance (laser stimulation: warmth or pinprick sensation). Laser stimuli were delivered using a CO2 laser device. Temporal and spatial principal component analyses were employed to define and quantify the ERP component reliability. Statistical analyses revealed the existence of an abnormal pattern of pain expectancy in patients with fibromyalgia. Specifically, our results showed attenuated amplitudes at posterior lCNV component in anticipation of painful stimulation that was not found in healthy participants. In contrast, although larger P2 amplitudes to painful compared to innocuous events were shown, patients did not show any amplitude change in this laser-evoked response as a function of pain predictive cues (as occurred in the healthy control group). Additionally, analyses of the subjective perception of pain and reaction time indicated that laser stimuli preceded by pain cues were rated as more painful than those signaling non-pain expectancy and were associated with faster responses. Differences between groups were not found. The present findings suggest the presence of dysfunction in pain expectation mechanisms in fibromyalgia that eventually may make it difficult for patients to correctly interpret signs that prevent pain symptoms. Furthermore, the abnormal pattern in pain expectancy displayed by fibromyalgia patients could result in ineffective pain coping strategies. Understanding the neural correlates of pain processing and its modulatory factors is crucial to identify treatments for chronic pain syndromes.
Perfectionism, maladaptive beliefs and anxiety in women with fibromyalgia. An explanatory model from the conflict of goals
(Elsevier, 2021) Gutierrez, Lorena; Velasco, Lilian; Blanco, Sheila; Catala, Patricia; Pastor-Mira, María Ángeles; Peñacoba, Cecilia
Fibromyalgia (FM) patients are known to be highly demanding of themselves in achieving goals. In fact, some authors suggest that perfectionism influences maladaptive coping regarding health and hinders routine tasks. Despite the evidence about the anxiety caused by this demanding pattern and the difficulty it creates in dealing with the conflict between goals, to date, there are no studies exploring the relationship between these psychological processes from motivational theories of pain. This study aims to explore the mediating role of pain catastrophizing and cognitive fusion between maladaptive perfectionism and anxiety among 230 FM women. Results found that pain catastrophizing and cognitive fusion contribute to the negative effect of maladaptive perfectionism on anxiety. These results can be interpreted from motivational theories of pain (conflict of goals), allowing action guidelines for the personalization of treatments.
Recursos cognitivos de percepción de control, procesos
(Psichotema, 2009) González, José Luis; Peñacoba, Cecilia; Velasco, Lilian; López, Almudena; Mercado, Francisco; Barjola, Paloma
El presente estudio evalúa un modelo estructural de relaciones entre los recursos cognitivos de control percibido sobre la enfermedad (expectativas de autoeficacia y lugar de control interno de dolor), el estado de estrés-recuperación y el malestar afectivo en mujeres con fibromialgia (n= 130). Los resultados fueron consistentes con la propuesta de que el balance de estrés-recuperación media la relación entre los recursos cognitivos y el malestar afectivo. Asimismo, se observó la presencia de un efecto directo por parte de los recursos cognitivos sobre la limitación funcional, mientras que la intensidad de dolor y los otros síntomas de enfermedad fueron directamente predictores del malestar afectivo. Teniendo en cuenta estos resultados, se señala la posible interpretación de una buena parte de las técnicas cognitivo-conductuales utilizadas habitualmente para el tratamiento de la fibromialgia, como herramientas orientadas a la búsqueda del correcto equilibrio entre estrés y recuperación, resultandofundamental para ello la modificación de las creencias de autoeficacia y las expectativas de control.
Resilience and Anxiety among Intensive Care Unit professionals during the COVID-19 pandemic
(Wiley, 2021) Gil, Fernanda; Carmona-Monge, Francisco Javier; Velasco, Lilian; García-Hedrera, Fernando Jose; Catalá, Patricia; Peñacoba, Cecilia
Background: The situation of the COVID-19 global pandemic has generated an unprecedented state of emergency worldwide that has had a psychological impact on health care workers working in the ICU and this has created the need to implement different psychological strategies. Aim: This study explores (a) the prevalence of symptoms associated with generalized anxiety disorder (GAD), (b) the relationship between GAD symptoms and resilience skills, and (c) which of the resilience skills were associated with a probable GAD among the ICU professionals during the COVID-19 pandemic. Study design: Cross-sectional survey design. Methods: We explored anxiety and resilience in 448 ICU health care workers using an online survey. Results: The participants showed high resilience levels and more than half of them presented symptoms consistent with a possible diagnosis of GAD. The GAD symptoms were more prevalent among women, nursing assistants, interns, staff who worked on rotation and health care workers who had to attend to more than 20 COVID patients. Significant negative correlations between resilience skills and GAD symptoms were found. The multiple regression analysis showed that resilience skills contribute to 14.4% of the variance for GAD symptoms. The binary logistic regression showed that the only skill that had a significant and negative predictive effect was “I usually take things in my stride” (OR = 0.774, 95% CI 0.67, 0.88; P = .000). This ability was the differentiating skill between professionals who equal or exceed the cut-off point established for the diagnosis of a probable GAD regarding those who do not. Conclusion: ICU professionals developed symptoms consistent with a possible diagnosis of GAD due to their exposure to extremely stressful circumstances. However, resilience skills acted as a protective factor. Relevance to clinical practice: The importance of incorporating programmes that mitigate these psychological effects and to promote adaptive coping styles during pandemics has become a need after what ICU professionals have gone through.
Stress and quality of life of intensive care nurses during the COVID-19 pandemic: Self-efficacy and resilience as resources
(Wiley, 2021-07-13) Peñacoba, Cecilia; Catalá Mesón, Patricia; Velasco, Lilian; Carmona-Monge, Francisco Javier; Garcia-Hedrera, Fernando J.
Abstract Background Health care workers employed in the COVID-19 emergency are at a high risk of stress. Aims and objectives To explore the mediating roles of self-efficacy and resilience between stress and both physical and mental quality-of-life components in intensive care nurses during the COVID-19 pandemic. Design Cross-sectional survey design. Methods The stress subscale (depression, anxiety, and stress scale in Spanish Scale, DASS-21), the summary components (physical and mental) of health-related quality of life (SF-36), the general self-efficacy scale (GSES), and the resilience scale (RS-14) were administered in 308 intensive care nurses. Serial multiple mediator models were used. Results There was a significant indirect effect of levels of perceived stress on both physical and mental health components through self-efficacy and resilience. Specifically, greater perception of self-efficacy was associated with a lower perception of stress and greater resilience, while higher resilience was associated with greater physical and mental health (B = −0.03; SE = 0.02; 95% confidence interval [CI] = [−0.07, −0.01]; B = −0.03, SE = 0.01, 95% CI = [−0.07, −0.01], respectively). It was observed that self-efficacy alone also mediates the relationship of the perception of stress on the components of physical and mental health (B = −0.07; SE = 0.05; 95% CI = [−0.18, −0.03]; B = −0.09; SE = 0.04; 95% CI = [−0.17, −0.24], respectively). However, resilience alone was not a significant mediator of these associations. Conclusions It can be concluded that stress is linked to the physical and mental health components related to quality of life through self-efficacy and resilience. Relevance to clinical practice These psychological resources would allow the nursing staff to maintain a good quality of life despite high levels of stress. These findings have implications for future research in terms of both model testing and clinical application.

(Springer, 2022) López-Gómez, Irene; Velasco, Lilian; Gutiérrez, Lorena; Écija, Carmen; Catalá, Patricia; Peñacoba-Puente, Cecilia
Introduction Walking is an efective treatment for symptoms’ management in patients with fbromyalgia. However, despite its benefts, fbromyalgia patients face a variety of obstacles that result in reduced ability to sustain physical exercise. The main goal of the study was to analyze the role of pain catastrophizing and fbromyalgia impact in the relationship between regular walking behavior and pain and fatigue experienced after a laboratory walking test. Method The study has an observational analytical laboratory design. A total of 100 women were contacted by the research team. Seventy-six women diagnosed with fbromyalgia aged 18 years and older (mean age=55.05, SD=7.69) participated. Results Signifcant correlations were found among regular walking behavior, pain catastrophizing, impact of fbromyalgia, pain intensity after walking, and fatigue intensity after walking. The serial multiple mediation analyses confrmed that pain catastrophizing and impact of fbromyalgia mediated the relationship between regular walking behavior and the level of pain (beta B=0.044, 95% CI=[0.01–0.012]) and fatigue (beta B=0.028, 95% CI=[0.01–0.08]) after the laboratory walking test. Also, the participants that walked less regularly experienced more pain and fatigue after the 6-Minute Walk Test. Conclusions Considering cognitive variables alongside the impact of fbromyalgia will help understand the inhibitors of engaging in physical activity. Therapeutic walking programs must be tailored to patients with fbromyalgia to reduce pain and fatigue related to physical activity and to promote better functioning and quality of life.
When it hurts, a positive attitude may help. The moderating effect of positive affect on the relationship between walking, depression and symptoms in women with fibromyalgia
(Elsevier, 2022) Ecija, Carmen; Catala, Patricia; Velasco, Lilian; Pastor-Mira, Mª Angeles; Peñacoba, Cecilia
Background: Increased exercise is a marker of health in fibromyalgia (FM). However, patients frequently avoid physical activity as a way of minimizing the pain they feel. This deprives them of opportunities to obtain positive reinforcement, increasing functional impact. Aims: This study examines the mediating role of depressive symptoms between walking (as physical exercise), functional impact, and pain, at different levels of positive affect (PA) among women with fibromyalgia. Design: Cross-sectional correlational study. Settings: Mutual aid associations for fibromyalgia in Spain. Participants: 231 women diagnosed with FM. Methods: Moderate mediation analyses were conducted using PROCESS. Results: First, a simple mediation model showed that depression mediated the effect of walking on functional impact, but not on pain. Additionally, the moderated mediated model showed that this effect was significant at medium and high levels of PA, but not when levels of PA were low. Conclusions: Provision of resources focused on positive affect seem to increase the positive effects of walking on functional impact through the reduction of depressive symptoms. Nurses can improve adherence of patients with FM to walking behavior through increasing positive affect.
